 to build into their structures as the Egyptians did. 



The diameter of a circle whose circumference is 2880 feet, is 

 916. 7320^- feet, and 2880 is a multiple of 24, for 24X120=^2880. 

 We have seen how intimately the numbers loSo and 1050 are 

 connected with 24 and 42, and how favorite a use the reversals of 

 numbers are, as i?, 21, 24, 42; and so we might note it of 103 as 

 501, and 108 as 801. 



Now the base side of The Great Egyptian Pyramid is 763. 943 -p 

 feet, or diameter of a circle whose circumference would be 2400 

 feet. 763.9434-feet is 9167.320-l-inches, which number, divided 

 by 10, is 916.7320, or in feet the diameter of the Newark Mound 

 circle. But we can carry the connection further. The half base 

 side of The Great Pyramid is 381.971-l-feet, and yV^''^ of this is 

 343.7745 [feet. This is the length of The Descending Passage 

 Way, in the pyramid. But 343.7745] is the diameter of a circle 

 whose circumference is 1080, and ■7^i\T^'].']^i^-{- minutes, is radius 

 minutes of the circle whose circumference is 360 degrees. All the 

 interior construction of the pyramid is built upon the use of the 

 length of this passage way, which is 200 Nilometer cubits. So, also, 

 the Hebrew divisions of time, the least and greatest, in the year, were 

 embraced by the number 1080 (Basnage).* 



One word more and we will finish. The reversed use of 

 numbers is a favorite one with the old Hebrews in their Sacred 

 Records. Here, with the Mound iUiilders, the writer finds it 

 again, and these are the only instances of his finding it, with the 

 one solitary exce[)tion of the measures of the rectangular area to 

 make one British acre, wherein such area is 528X10=5280 feet 

 long by 8.25 feet in width, the numerical value 528 being reversed 

 to 825 (8.25 feet being the half of one rod). 



After the close of the above, the writer visited Col. Charles 

 Whittlesey, in Cleveland, Ohio, who personally assured him of the 

 accuracy of the measures of the mound works referred to in the 

 foregoing. He also stated that he, himself, had a manuscript lately 

 completed, his own independent attempt at finding the standard of 

 measure of the Mound Builders. He obtained it by finding an 

 even factor "which would api)ly in common, with various multii)les, 

 to some eighty measures of the mounds, selected as within his own
